双氧水法制水合肼中间体提纯的数值模拟
Numerical studies about intermediate purification of using hydrogen peroxide to produce hydrazine hydrate
摘要
Abstract
In the process of using hydrogen peroxide to produce hydrazine hydrate, the impurity was separated by the dividing wall column after the study on separation. Aspen Plus was used to simulation the process of isolation and purification of the components. The effect of factors such as feed location, feed temperature, reflux ratio and tower pressure were studied. The best process operating parameters were obtained to provide theoretical basis for the technology. The molar ratio of impurities to butanone collected from the top of the column was 0.023<0.03, reaching the standard for recovery. After optimization, 14.1% and 10.8% of the energy consumption of condenser and reboiler was saved, respectively. The theoretical plate number of main tower and deputy tower was 42 and 14, respectively. The feed position was 13 boards and the reflux ratio was 7 under operation pressure of 0.101 MPa. The percentage of the methyl ethyl ketone azine from the bottom of the tower was 98.2%.关键词
